Main Components

Carrier/Chassis – The mobile base that supports all components; can be diesel, electric, or hybrid powered.

Booms – Articulated arms that hold and maneuver the drills. Jumbos may have 1, 2, or 3 booms depending on tunnel size and productivity needs.

Rock Drills – Pneumatic or hydraulic drills mounted at the boom’s end.

Control System – Manual, semi-automatic, or fully computerized drilling control for precision hole placement.

Operator Cabin – Provides a safe, comfortable space for the operator with good visibility and controls.

Jumbo Drilling Rig Applications

Underground mining – Ore development headings, crosscuts, and production drilling.

Tunneling projects – Road, rail, or water tunnels.

Hydropower construction – Underground caverns and penstock tunnels.

Civil infrastructure – Metro systems, underground parking, sewer systems.

How It Works

Positioning – The jumbo moves into place in the tunnel or heading.

Boom Setup – Operator adjusts the boom(s) and drill(s) according to the blast pattern or bolt placement plan.

Drilling – The rock drill penetrates the rock to the required depth, flushing cuttings with water or air.

Blasting or Bolting – After drilling, holes can be loaded with explosives for blasting, or bolts for ground support.

Types of Jumbo Drilling Rigs

Single-boom jumbo – For small tunnels or confined spaces.

Double-boom jumbo – Balanced productivity for medium-sized headings.

Triple-boom jumbo – High-capacity drilling for large tunnels and heavy-duty mining.
